Perturbative instability of cosmology from quantum potential
- Physics
- 2016
Apart from its debatable correctness, we examine the perturbative stability of the recently proposed cosmology from quantum potential. We find that the proposed quantum corrections invoke additional…

Recently, Ali and Khalil (Nucl Phys B, 909, 173–185, 2016), based on Bohmian quantum mechanics, derived a quantum corrected version of the Schwarzschild metric. In this paper, we construct a quantum…
On the correctness of cosmology from quantum potential
- Physics

We examine in detail the cosmology based on quantal (Bohmian) trajectories as suggested in a recent study arXiv:1404.3093[gr-qc]. We disagree with the conclusions regarding predicting the value of…
Quantum Hǒrava-Lifshitz cosmology in the de Broglie–Bohm interpretation
- PhysicsPhysical Review D

Taking a quantum corrected form of Raychaudhuri equation in a geometric background described by a Lorentz-violating massive theory of gravity, we go through investigating a time-like congruence of…
Quantum cosmology of a Hořava–Lifshitz model coupled to radiation

We derive the equations of cosmological evolution from an anti-de Sitter-Schwarzschild black hole via holographic renormalization with appropriate boundary conditions.
Quantum Raychaudhuri equation

- 2014
We compute quantum corrections to the Raychaudhuri equation, by replacing classical geodesics with quantal (Bohmian) trajectories, and show that they prevent focusing of geodesics, and the formation…
Quantum dynamics with Bohmian trajectories.
- PhysicsThe journal of physical chemistry. A
- 2007
This work focuses on the crucial noncrossing property of Bohmian trajectories, which, numerically, must be given careful attention, which causes instabilities or leads to false simulations.
Quantumness beyond quantum mechanics

Bohmian mechanics allows us to understand quantum systems in the light of other quantum traits than the well-known ones (coherence, diraction, interference, tunnelling, discreteness, entanglement,…
